Evaluation of equine synovial-derived extracellular matrix scaffolds seeded with equine synovial-derived mesenchymal stem cells.

OBJECTIVE To create a bioactive synovium scaffold by infusing decellularized synovial-derived extracellular matrix (synECM) with synovial-derived mesenchymal stem cells (synMSCs). SAMPLE Synovium from the femoropatellar and medial femorotibial joints of equine cadavers. PROCEDURES The synMSCs were cultured in monolayer and not treated or cotransduced to enhance expression of green fluorescent protein (GFP) and human bone morphogenetic protein (BMP)-2.

Comparison of four methods for generating decellularized equine synovial extracellular matrix.

OBJECTIVE To evaluate 4 methods for generating decellularized equine synovial extracellular matrix. SAMPLE Villous synovium harvested from the femoropatellar and medial femorotibial joints of 4 healthy adult horses < 7 years of age. Synovial samples were frozen (-80°C) until used.
